"UniverseMachine" churns out millions of unique universes to study dark matter and the evolution of galaxies.

What are the building blocks of everything that makes up the universe, and where did it all come from?

There are bright lights all over the universe where galaxies are smashing together. And now astronomers have a new way to find them.

Two theoretical physicists propose a novel idea to find dark matter — and it might actually be testable.

Several giant experiments are hunting for neutrinos, the tiniest, most-elusive particles in the universe.

Extremely hot materials show off their temperature by doing the twist.

Supergravity has inspired physicists for decades and may contain deep truths about the nature of reality.

The proof took 30 years to be solved, but it's so simple and elegant that you can summarize it in a single tweet.

In a new paper, a pair of Japanese astronomers hatch a plan for finding dozens or hundreds of the black holes that are hiding out in the Milky Way.

The next step, researchers said, is to figure out whether it has an atmosphere.

Halos aren’t just for angels.

A peculiar atmospheric process is sculpting meteorites into surprising shapes as they fall.

A Chinese space station fell out of the sky today (July 19). But unlike the last time this happened, China was in control the whole time.

Scientists just captured the first-ever photo of a "spooky" quantum physics phenomenon.

Tiny ripples called magnons could lure even a fleeting, lightweight dark matter particle out of hiding.

Scientists know very little about the faults that ripped apart during the massive SoCal quakes.

NASA's new exoplanet-hunting telescope has discovered its smallest planet yet: a world somewhere between the sizes of Earth and its smaller sister, Mars.

A team of researchers have posted a paper in which they claim to have achieved a holy grail of materials science: creating metallic hydrogen in a laboratory.

There's a strange object in the Milky Way that blinks at us once or twice a day, and a team of scientists think they've figured out why.
